Like UITableView, EKStreamView renders many cells having almost the same structure by resuing the cell views whenever possible. It's fast even you have hundreds of cells since only a small number of cells are actually created.
Copy EKStreamView.h and EKStreamView.m to your project. This class is ARC-enabled. You must build it with ARC.
Implement the required methods in EKStreamViewDelegate protocol, and implement the optional ones optionally. This class acts very similar as UITableView. However, in a UITableView, your cell should subclass UITableViewCell, while in EKStreamView, your cell is only required to conform to the protocol EKResusableCell to provide a reuse ID.
